SPECIFICATION forming part of Letters Patent No. 690,038, dated December 31, 1901.

Application filed July 11, 1901. Serial No. 67,826. (No model.)

To (tZZ whom, it may 007200772:

Be it known that I, FREDERICK H. SIMES, a citizen of the United States, residing at Milton Mills, in the county of Strafford and State of New Hampshire,have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. In fancy looms using change shuttle boxes for weaving goods having a body of one color and transverse stripes of a different color to constitute borders, as in blankets, 850., the color of the border being determined by calling into operation shuttles containing weft of the desired color, it is customary to employ with the shuttle-box pattern-chain a multiplying pattern-chain which moves with the shed-forming pattern-chain while the body of the blanket is being woven, the multiplying-chain starting into operation and moving the shuttle-box chain at intervals to thereby bring into operation a shuttle having the desired color. The multiplying-chain also acts to retain the shuttle-box chain at rest if two or more like picks are to be made in succession. I desire to not only shorten the multiplying-chain, but also to obviate moving the same only when the shuttle-boxes containing 0 the weft for transverse striping is to be used.

Ordinarily, as stated, the multiplying pattern-chain has a bar for each shed to receive a pick in the weaving of the body of the blanket or fabric, and during this time the shuttle-box pattern-chain remains at rest, the multiplying pattern-chain having other bars to actuate the shuttle-box pattern-chain having suitable indicators on their bars to actuate the shuttle-box pattern-chain when 0 a shuttle-box having a shuttle containing a weft of a desired color is to be called. In my invention I have provided means whereby the multiplying pattern-chain and the shuttle-box pattern-chain are both at rest while 5 the body of the fabric in one color is being woven, and by leaving the multiplying-chain stationary or at rest at such time it becomes possible to shorten the chain by as many bars less one as the number of picks required to make the body of the blanket in one color, and, further, by leaving the chain idle during the weaving of the body of the blanket or other fabric I greatly reduce the power required in running the loom.

Figure 1, in side elevation and partial section, represents a sufficient portion of a wellknown loom with my improvements added to enable my invention to be understood. Fig. 2 is a sectional detail below the line at, to be referred to. Fig. 3 shows adouble pinion, such as now ordinarily employed in the Knowles loom.

The top frame D, the toothed elevator and depressor gears O and E, driven constantly and engaging at suitable intervals the crankgears H, connected operatively with the moving shed-forming levers O, and the pinion d, engaging and rotating the gear K, fast on the shaft 1, carrying the shed-forming patternchain, (not shown,) having projections for lifting the levers B to put the gears H in engagemcnt with either the elevator or depressor gears, are substantially such as employed in well-known Knowles looms, a type of which is represented in United States Patent No. 134,992, dated July 21, 1873, and in Patent No. 413,369, dated October 22, 1889, showing an improved variety of said Knowles loom. The shaft 19, common to Patent No. 413,369, has secured to it at one end two pin-wheels, (not shown, but fully shown and described in said patent,) which engage and move at the proper times two star-wheels, which actuate, as provided forin said patent, the usual multiplying pattern-chain and the box patternchain.

In looms of this class as now made the shaft 19 is rotated continuously by or through a double pinion (see Fig. 3) made in one piece, the smaller diameter 2 being driven by the gear K and causing the pinion 3 of larger diameter in engagement with the pinion 4 on the shaft 19 to rotate said shaft and its pinwheels continuously, one or the other pinwheel actuating either the multiplying-chain or the shuttle-box chain through suitable indications carried by the shed-form ing patternchain. In my invention I have done away with the double pinion 2 3 referred to and commonly used in the Knowles loom, and in- :00

extended from the frame part D. The pinion a has a shank or hub (2, provided with a groove a which is entered by the forked end of a suitable lever a mounted on a stud a 5 and adapted to be held in one or the other of its two positions by a suitable locking device a which may be a spring-arm. The pinion a may he slid out and in on the stud c, and it is always rotated, and it is left always in engagement with the gear K and is rotated constantly thereby. The two pinions a and b are adapted to act as clutches, so that when the pinion a is drawn outwardly it may be unclutched from the pinion b,and the latter will be left at rest and also the shaft 19, carrying the usual star-wheels for actuating the multiplying pattern -chain and the shuttle-box pattern-chain.

are coupled together, the pinion a immedizo ately takes up with it and starts the pinion b,

and the latter instantly starts the shaft 19.

Toeffect the coupling of the pinions a and b, I' have provided one pinion (shown as a) Y with a stud 5 and the other (shown as b) with a hole 6, and whenever the pinions are moved to cause the stud 5 to enter the hole 6 then the moving pinion a will start up with it the pinion b, and the latter, in engagement with the pinion at, willstart the shaft 19, thus start- 0 ing the multiplying-chain, the latter starting at proper times the box-chain, and the shaft 19 will be rotated continuously as long as the pinions are coupled together, and whenever the pinions are unclutched the shaft 19 will again be left at rest. Herein I have chosen to illustrate the pinion a as actuated to engage and drive the pinion b by a lever which is manually controlled but it is obvious that I might employ a suitable device shaped as a cam moved intermittingly at each pick, and said device or cam after the number of picks had been inserted necessary to weave the body of one color might move the lever or otherwise effect the coupling of the pinions 5 a and b, the device or carn effecting the uncoupling of said pinions after the number of picks necessary to weave the border, of whatever width, had been inserted.

The two pinions a and b, as described, constitute one form of clutch, and instead of the particular means for coupling the pinions a and I) together I may employ any other usual or suitable equivalent means. By the employment, however, of the pin and hole the WVhenever the two clutches pinion b is always picked up and started from just the position where it was left when the pinion a was uncoupled from it, and inasmuch as the pinion b is the effective one in moving the shaft 19 the proper order of movement of the pinion b is always maintained.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a loom, a shaft for actuating the shedforming pattern-chain, a gear movable in unison with said shaft, a shaft as 19 instrumen tal in actuating the usual multiplying-chain and the usual shuttle-box chain, a pinion a, moved continuously by said gear, a second pinion b, in engagement with a pinion on said shaft, and means to couple said pinions aand b together when the shaft 19 is to be rotated, said pinionsv being uncoupled to leave the pinion engaging the pinion on said shaft at rest while the body of the article being made is being woven.

2. In a loom, a shaft I adapted to carrythe usual shed-forming pattern-chain, a gear on said shaft, means to move said gear with its said shaft, a pinion engaged by said gear and rotated continuously thereby, a shaft 19 adapted when moved to actuate a multiplying pattern-chain and a shuttle-box chain, a pinion engaging a pinion on said shaft 19, and means to cause the pinion movedr con,- stantly by the gear on the shaft I to engage the pinion meshing with the pinion on the shaft 19, to start said shaft 19 when the fabric being woven is to present cross-stripesfor. a border; 0

3. In a loom, a rotating depressor-gear provided with a pinion, a gearK rotated continuously by said pinion, a shaft 19 adapted to actuate a multiplying pattern-chain and a shuttle-box pattern-chain, a pinion on said shaft 19, a pinion b engaging the pinion on the shaft 19, and means to cause the pinion a to engage ahd move with it at suitable intervals the pinion b, said means at suitable times causing the pinion a to be unclutched from the pinion b to leave the latter at rest.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FREDERICK H. SIMES.
